Homebrew TWPatcher - DS(i) mode screen filters and patches

[Rahkeesh]

Out of the LgyBG cons you listed I think the only one your average user is going to care about is needing to use VC injects instead of a rom browser.

Don't sell yourself short on graphics, open_agb_firm has a neat filter but it should pale in comparison to 800px scaling yielding perfect horizontal integer scale, requiring only vertical interpolation. (Although this seems like something that could be added to open_agb_firm in theory?) The saturated colors seem to derive from simply setting a gamma curve, maybe not too hard for you either?

Anyway very excited to see this stuff for GBA and looking forward to whatever comes of it!

Pretty sure there is a camp of similar size for both those who stand by VC injects, and those who just want to load stuff from the SD. Perhaps nowdays it's more the latter, especially because you can't do VC injects on the 3DS itself, and setting up all the assets and other stuff is quite painful indeed.

And yes, there is nothing (well, except pain and time) preventing profi200 from adding mode800 support to open_agb_firm.
And yes, there is nothing (except sweating piss and limited time and energy because of work) preventing me from doing LUT calculations. Hell, I'm already doing it for redshift, soooooooo...

And back to the VC inject thing... pretty sure our things won't compete with eachother, because both will have a similar feature set, with the only important difference being that his loads from SD and saves next to the ROM files, whereas mine still works like it would unmodified, except with better features than the original. This is why I'll promote open_agb_firm (and open_twl_firm if it happens) in the thread I'll create once I get GPU rendering working.

New TWPatch update to get ready for LgyBg support:

• added new kernel patches to make LgyBg functional
• unlocked the kernel patch menu, so it's easier to access now (Y+B, X+A, START, SELECT)

LgyBg's GBA mode is pretty close to alpha release.

For DS mode, I still need to get touch, datetime, and DSi-specific stuff working.

Question about LgyBg: Will the link cable be supported in some form, possibly through wireless communication? It's ok if it isn't, since link cable functionality seems to be hard to implement on 3DS.

I installed the patch and selected one of the filters. I have a DS cartridge I tried using by the filter didn't apply. Anything I need to do in order to make it work?

Make sure that you enable external FIRM loading in Luma3DS. (Hold Select on boot, it's the 7th option from the bottom)

Make sure external FIRMS and modules are turned on in the Luma config menu.

Did you enable loading of external modules in Luma settings?

Edit: Welp, double ninja'ed.

Hold Select button when turning your 3DS on.

 

[RubyOtaku]

Yep that was it. Thanks!

 

[ccfman2004]

Glad to hear.

To my knowledge the link cable hardware doesn't exist inside the 3DS. Personally I haven't tested it, becase I don't know enough to make GBA homebrew; I only know 3DS.

 

[Rahkeesh]

GBARunner2 has some tentative work emulating link cable over wi-fi.

Note that they only have access to wi-fi because it is running in DS mode.

Short answer: No.
Long answer: The SIO/link port is stubbed in hardware just like it was on DS. The best you can hope for is wireless adapter support but only with heavy patching and cursed tricks. Link cable isn't really doable due to needing extremely low latency. GBARunner2 can sort of workaround the latency issue by throttling the game but it's still flaky.

Does anyone have a saved version of this from April 2020? I updated from a version from around then today but I'm really missing that it only used widescreen for games that support it. I didn't prevously use any of the filters and I'm not seeing a big enough improvement from the GPU upscale to warrant losing the convenience of automatic aspect ratio swapping.

@Sono This is amazing. Hope to see releases soon. Thanks for supporting the community.

Actually I'm very confused now because I redid the patch without widescreen and while everything is in 4:3, games like Chinatown wars and super Mario 64 are in widescreen... So my problem is fixed!

Hi all, made an account because I'm having some trouble with using widescreen on my N3DS. The widescreen patch works great in games like Super Mario 64. But DS games that don't support widescreen, also display as 16:10. Changing the individual setting doesn't work. Even if I revert the TW++ setting back to 4:3, everything remains stretched. Any solutions to this problem?

That's normal in later TWLMenu++ versions, as per-game widescreen wasn't working for some users.
To revert back to 4:3, delete "TwlBg.cxi" at "sd:/luma/sysmodules/".
